>Looks like yet another Maxima expression we'll need to build into Sage: ?%ilt must be a nounform for inverse laplace transform that Maxima can't give a closed form for. I'm mystified by the "false" stuff, though - David J. or Robert M., you guys understand the Maxima desolvers, any ideas? Of course, it would be worth seeing whether one of the other CASs can solve this one exactly. - kcrisman --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
